近年來,隨著國內(nèi)外大批的太陽能光伏電站的建立和并網(wǎng)發(fā)電,作為光伏發(fā)電的關(guān)鍵設(shè)備光伏并網(wǎng)逆變器具有廣闊的市場前景。
本文主要介紹WEINVIEW觸摸屏在太陽能光伏并網(wǎng)逆變器中的應(yīng)用,在這個系統(tǒng)中,觸摸屏和逆變控制器通信,完成相關(guān)的數(shù)據(jù)采集,資料的保存,報警信息的登錄,圖文并茂顯示逆變器運行參數(shù)和實時狀態(tài),并通過485或以太網(wǎng)和上位計算機進行遠程通訊,實現(xiàn)整個并網(wǎng)電站的實時監(jiān)控和調(diào)配。

1 引言
隨著全球經(jīng)濟的迅猛發(fā)展,各行業(yè)能耗加劇,石油、煤炭等傳統(tǒng)化石能源日趨枯竭。世界各國都把目光投向了可再生能源,希望可再生能源改變?nèi)祟惖哪茉唇Y(jié)構(gòu),維持長遠的可持續(xù)發(fā)展。在可再生能源中,太陽能以其獨有的優(yōu)勢而成為人們關(guān)注的焦點。太陽能是取之不盡、用之不竭、無污染的綠色能源。世界各國都在投入巨資建設(shè)大規(guī)模的太陽能發(fā)電站。我國在光伏研究和產(chǎn)業(yè)方面也取得了較快的進展,2006年1月1日實施的《可再生能源法》,標志著太陽能發(fā)電已納入我國的能源發(fā)展規(guī)劃之中。根據(jù)2007年9月發(fā)布的《可再生能源中長期發(fā)展規(guī)劃》,2020年,我國太陽能發(fā)電設(shè)備累計裝機容量將達到2000MW 。
太陽能光伏并網(wǎng)逆變器是整個光伏發(fā)電系統(tǒng)中最為關(guān)鍵的設(shè)備之一,它是把太陽能電池板產(chǎn)生的直流電能轉(zhuǎn)換為交流電能的設(shè)備,運行過程中需要多個參數(shù)進行監(jiān)測、計算、顯示、記錄、保存、報警等處理,需要和上位計算機、逆變控制器、無線GPRS模塊進行通訊,實現(xiàn)數(shù)據(jù)交換。本文主要講述WEINVIEW觸摸屏在太陽能光伏并網(wǎng)逆變器中的應(yīng)用。
2 系統(tǒng)原理和方案設(shè)計
太陽能光伏并網(wǎng)逆變器是把太陽能電池板通過光伏效應(yīng)產(chǎn)生的直流電能進行逆變,轉(zhuǎn)換成同電網(wǎng)同頻率、同相位的交流電,接入電網(wǎng)對外進行輸電。逆變器運行中要把測量的實時參數(shù)送給觸摸屏,進行顯示、記錄等操作,也可和上位機通訊進行遠程監(jiān)控功能。系統(tǒng)結(jié)構(gòu)圖如下圖所示:

3 WEINVIEW畫面設(shè)計要求
本系統(tǒng)采用WEINVIEW MT8100I型號觸摸屏,高品質(zhì)10寸寬屏設(shè)計,LED背光模組;采用400MHz RISC CPU,使運行速度更快;內(nèi)置電源隔離保護器,提高了產(chǎn)品的抗干擾能力,適應(yīng)復(fù)雜環(huán)境下運行;多種標準的通訊接口和網(wǎng)絡(luò)協(xié)議,方便用戶使用;大容量的數(shù)據(jù)存儲功能,并且可以直接存儲或備份到U盤、SD卡或上位機上,滿足逆變器運行過程中產(chǎn)生的海量數(shù)據(jù)信息。
3.1 觸摸屏主界面設(shè)計
主界面顯示逆變器運行的各種運行參數(shù):PV電壓、PV電流、A、B、C三項交流電壓和電流、功率因數(shù)、電網(wǎng)頻率、輸出功率、日發(fā)電量、總發(fā)電量、CO2減排量等,逆變器運行狀態(tài)指示,實時時間,以及其他操作菜單。下圖分別是主界面的中英文顯示菜單。
